SPRINGFIELD — A fire that broke out in the third floor of a two-family home at 571 Dickinson St. on Tuesday evening caused an estimated $80,000 damage and displaced four residents, a fire official said.

Dennis Leger, aide to Fire Commissioner Joseph Conant, said the fire appeared to have started in the rear of the house on the third floor. From there it went up in to the roof and attic.

The fire was reported shortly after 6 p.m.

Large sections of the roof were heavily damaged by the fire and had to be cut away by firefighters.

Leger said the exact cause has not been found, but investigators with the city Arson and Bomb Squad are investigating.

No residents were injured in the fire but some firefighters were treated at the scene after suffering bits of debris in their eyes, he said.

Leger said the fire is out and firefighters remained on the scene mopping up. Dickinson Street, which was closed off to traffic in both directions between Trafton Road and Biltmore Street, was expected to remain closed through about 9:40 p.m., Leger said.
